OBJECTIVE:#To connect solutions in graphs and tables to solutions of equations. #To find a solution common to two linear equatons by graphing. # to understand how the y-intercept appears in tables and equations. #to understand how the rate of change (the coefficient m) appears in equations and affects the graph of a line. ACTIVITIES: Page 36 Problem 3.1 NOTES: Ordered Pair; coordinates; Review Quadrants. Students will need to graph and make table for problem 2.3 first. Then they will continue on that paper with 3.1, "Getting to the Point" on page 36 HOMEWORK: P36 follow up 1 and 2A. Read the question carefully and ANSWER the QUESTION!

How to create a data table and make a coordinate graph from an equation.

Suppose we have an equation like:

y=3x-2

To make a graph from this (or a similar equation) we do the following:

• Determine the variables - in this case x and y.
• Make table with two columns labelled x and y.
  

  x	y

  
  
• Now you must decide which variable you wish to substitute first - x or y.
  Let's do x=1. Substituting 1 in place of x gives us y=(3*1) -2, which is 1. Now we put the value in the table and pick another...

  x	y
  1	1

  
  
• Next we can substitute a 2 for x. That gives y = (3*2)-2 which equals 4.
  

  x	y
  1	1
  2	4

  
  
• Continue until you have 4 or 5 values for your data table and then make your x-y coordinate plot.
